Abstract (en)
[origin: WO2016131721A1] The invention relates to a method for characterising a fault affecting a cable, into which a time-limited support reference signal s is fed and a measurement r is made of the reflection of said reference signal s in the cable. Said method is characterised in that said method includes the following steps: identifying (201) a portion of the measurement r that corresponds to a fault, this measurement portion being referred to as the fault signature; generating (202) a modified reference signal s' that has a parameterisable amplitude and that is equal to the sum of said reference signal s and said reference signal s that is inverted and delayed by a parameterisable delay; collectively determining (203) the parameterisable delay values and the parameterisable amplitude values that minimise the error between the modified reference signal s' and the fault signature; deriving (204) therefrom an estimate of the length of the fault starting from the value of said predetermined delay.
